Permana, Andiny Aulia Putri (2018) Pemanfaatan Zeolit Aktif dalam Penurunan Konsentrasi Amonia dan Nilai BOD menggunakan Metode Adrsorpsi pada Air Sungai Tercemar Sub-Sub DAS Bango. Sarjana thesis, Universitas Brawijaya.
Abstract
Sebagai salah satu sumber daya alam, air sungai memegang peranan penting dalam kehidupan. Seiring berjalannya waktu, air sungai di Indonesia menjadi tercemar, salah satunya adalah air sungai sub-sub DAS Bango kota Malang. Pencemaran terjadi akibat pembuangan limbah peternakan tanpa mengalami proses pengolahan terlebih dahulu. Pencemaran air sungai dapat ditanggulangi, dengan metode adsorpsi menggunakan adsorben berupa zeolit. Zeolit yang digunakan terlebih dahulu di aktivasi secara fisika dan kimia. Penelitian ini bertujuan untuk mengetahui besar penurunan konsentrasi amonia dan nilai BOD setelah melewati proses adsorpsi, besar efisensi yang dihasilkan dari proses adsorpsi dalam penurunan konsentrasi amonia dan nilai BOD, serta mengetahui pengaruh kombinasi perlakuan waktu kontak dan massa adsorben zeolit aktif terhadap penurunan konsentrasi amonia dan nilai BOD air sungai tercemar sub-sub DAS Bango dalam proses adsorpsi. Penelitian ini menggunakan metode rancangan acak lengkap (RAL), dengan variasi perlakuan kombinasi antara faktor waktu kontak dan faktor massa adsorben. Variasi perlakuan yang digunakan adalah : 2 gram zeolit aktif dan 30 menit waktu kontak; 2 gram zeolit aktif dan 60 menit waktu kontak; 4 gram zeolit aktif dan 30 menit waktu kontak; 4 gram zeolit aktif dan 60 menit waktu kontak. Berdasarkan hasil penelitian proses adsorpsi dapat menurunkan konsentrasi amonia dari 15,71 mg/l menjadi 14,101 mg/l hingga 7,484 mg/l, dan nilai BOD dapat turun dari 731,1 mg/l menjadi 704,433 mg/l hinga 556,1 mg/l. Efisiensi yang dihasilkan dari proses adsorpsi amonia berkisar antara 10,242 % hingga 52,363 %. Efisiensi yang dihasilkan dari proses adsorpsi untuk x menurunkan nilai BOD berkisar antara 3,647% hingga 23,937 %. Berdasarkan uji Anova dua jalur, kombinasi perlakuan waktu kontak dan massa adsorben zeolit aktif pada penelitian ini tidak berbeda nyata, dan tidak memberikan pengaruh signifikan dalam menurunkan konsentrasi amonia dan nilai BOD.
English Abstract
As one of natural resources, river water holds an important role in life. As the time goes, many of clean river water resources in Indonesia became polluted, one of them is Bango watershed in the city of Malang. The pollution occurred because of the untreated farm wastes disposal. The river water pollution could be treated using adsorption method with zeolites as adsorbent. The zeolite was phsically and chemically activated before it was used. The purposes of this research were to know how much of ammonia dan BOD concentration could be reducted by adsorption process, the efficiency of the process, and the effect of contact time factor and dosage of active zeolite adsorbent factor combination for reducting ammonia and BOD concentration in polluted water of Bango watershed. The research used complete randomized design as its method, with 4 treatment variations that combining between contact time factor and dosage of active zeolite adsorbent factor. The variations were : 2 grams of active zeolites and 30 minutes of contact time; 2 grams of active zeolites and 60 minutes of contact time; 4 grams of active zeolites and 30 minutes of contact time; 4 grams of active zeolites and 60 minutes of contact time. Based on the research, through the adsorption process ammonia concentration could be reducted from 15,71 mg/l to 14,101 mg/l up to 7,484 mg/l, and BOD concentration could be reducted from 731,1 mg/l to 704,433 mg/l up to 556,1 mg/l. The efficiency from adsorption process for reducting ammonia was 10,242 %, and up to 52,363 %. The efficiency from adsorption process for reducting BOD concentration was 3,647%, and up to xii 23,937 %. Based on the two way Anova test, the treatment variations made of contact time factor and dosage of active zeolite adsorbent factor combination used in this research were not signifficantly different, and didn’t give signifficant effect in reducting ammonia and BOD concentration.
